For its each TV transmitter 106 from this received television signal, each watch-dog 108 is measured the local clock of this TV transmitter and the time migration between the reference clock.In certain embodiments, this reference clock is derived by gps signal.When using a plurality of watch-dog 108, because each watch-dog 108 can be determined time migration with respect to reference clock, so the use of reference clock allows for the 106 definite time migrations of each TV transmitter.Therefore, the skew in the local clock of watch-dog 108 does not influence these and determines.Watch-dog 108 is described in detail in U.S. Patent Application Serial Number No.09/887, and is in 158,09/932,010 and 10/054,302, at this that its disclosure is whole in conjunction with as with reference to data.
In another embodiment, do not need external time reference.According to this embodiment, single watch-dog 108 is worked as user terminal 102, from all identical TV transmitter received television signals.In fact, the local clock of single watch-dog plays the effect of time reference.
In certain embodiments, each time migration is modeled as a kind of constant offset amount.In another embodiment, each time migration is modeled as a kind of second order polynomial match of following form:
Skew=a+b (t-T)+c (t-T) 2(1)
It can be described by a, b, c and T.In any one embodiment, modem connection that each time migration of measuring all utilizes the Internet, safety or the like periodically sends to location server.In certain embodiments, the position of each watch-dog 108 is determined with the GPS receiver.
Location server 110 receives the information of the phase center (being the position) of describing each TV transmitter 106 from database 112.In certain embodiments, the phase center of each TV transmitter 106 is measured by using watch-dog 108 direct Measurement Phase centers at diverse location.In another embodiment, the phase center of each TV transmitter 106 is measured by the observation antenna phase center.
In certain embodiments, location server 110 receives near the weather information that is described in air themperature, atmospheric pressure and the humidity user terminal 102 from a weather server 114.Weather information can obtain from the Internet and such as other such sources of National Oceanographic and Atmospheric Administration (NOAA).Location server 110 uses such as at B.Parkinson and J.Spilker, Jr. show disclosed method (AIAA in " GPS---theoretical and application ", Washington, DC, 1996, the first volume the 17th chapter " troposphere is for the influence of GPS ", by J.Spilker, Jr writes), determine tropospheric velocity of propagation by weather information.
Location server 110 can also receive the information from base station 104, the conventional geographic position of its identifying subscriber terminal 102.For example, information can identify a cell phone and is positioned at its sub-district or cell sector.This information is used to fuzzy resolution.
The mobile telephone signal (step 206) that user terminal 102 receives from one or more mobile telephone base stations 104.Mobile telephone signal can comprise distance signal, as GSM timing advance parameter.User terminal 102 is determined distance and/or the pseudorange (step 208) between this user terminal and each mobile telephone base station 104.This distance can obtain from distance signal, as is discussed in more detail below.A kind of composition that each pseudorange is represented mobile telephone signal is from time and the mistiming (perhaps Deng Xiao distance) of this composition between the time that mobile telephone base station 102 is received that mobile telephone base station 104 sends, and at the clock offset at mobile telephone base station place.User terminal 102 sends pseudorange to location server 110.
The position of the distance of location server 110, when using, each TV transmitter 106 based on pseudorange, and the position of mobile telephone base station 104 determine the position (step 210) of user terminal.Fig. 3 has described the geometric figure that uses 3 transmitters 302 to carry out position finding.Transmitter 302 can comprise any combination of TV transmitter and mobile telephone base station.Transmitter 302A is set at the position, and (x1, y1 z1) locate.Distance between user terminal 102 and the transmitter 302A is r1.Transmitter 302B is set at the position, and (x2, y2 z2) locate.Distance between user terminal 102 and the transmitter 302B is r2.Transmitter 302N is set at the position, and (x3, y3 z3) locate.Distance between user terminal 102 and the transmitter 302N is r3.
Location server 110 can be adjusted the numerical value of each pseudorange according to tropospheric velocity of propagation and the time migration that is used for corresponding transmitter 302.Location server 110 uses the position of removing to determine each transmitter 302 from the phase center information of database 112.Being used for the position of GSM base station and E-OTD auxiliary data broadcast message that clock offset can be transmitted from the GSM base station obtains.
User terminal 102 carry out three times or more times pseudo range measurement obtaining three unknown numbers, that is the position of user terminal 102 (x, y) and clock offset T.Suppose that within necessary accuracy the height of user terminal is known, only need accurately to determine the longitude and latitude of user terminal.Certainly, suppose that four or more a plurality of transmitter are available, and the geometric distributions of these transmitters is enough, then might obtains the position of user terminal in three dimensions, and promptly (x, y, z).To those skilled in the art, how to be adjusted at that described herein to be used for 3 dimension position fitting method will be conspicuous.
Described three pseudo-range measurements pr1, pr2 and pr3 are provided by following formula:
pr1＝r1+T (2)
pr2＝r2+T (3)
pr3＝r3+T (4)
These three distances can be expressed as:
r1＝|X-X1| (5)
r2＝|X-X2| (6)
r3＝|X-X3| (7)
Wherein X represents that (z), X1 represents the tri-vector position (x1 of transmitter 302A for x, y for the tri-vector position of user terminal, y1, z1), X2 represents tri-vector position (x2, the y2 of transmitter 302B, z2), and X3 represent transmitter 302N the tri-vector position (x3, y3, z3).These mutual relationships produce three equations, find the solution three unknown number x, y and T therein.Notice that under the situation that only needs longitude and latitude, about other unknown coordinates, location server 110 is supposed certain estimated value for z and it does not found the solution.In one embodiment, use a kind of topomap,, can improve the initial estimate of z repeatedly based on calculated value to x and y.In another embodiment, location server 110 is actively found the solution z.Location server 110 is found the solution these formula according to the known method of routine.In a kind of E911 used, the position of user terminal 102 was transmitted to E911 location server 116, gave appropriate authority so that divide.In another kind was used, this position was transmitted to user terminal 102.
In certain embodiments, user terminal 102 is compute pseudo-ranges not, but gets the signal measurements that is enough to calculate pseudorange, and sends these measured values to location server 110.Then, location server 110 is based on these measured value compute pseudo-ranges, and goes out the position based on its computation of pseudoranges, as mentioned above.
Position finding by the user terminal execution
In certain embodiments, the position of user terminal 102 is calculated by user terminal 102.In such an embodiment, the information that is necessary is transmitted to user terminal 102.This information can be transmitted to user terminal 102 by location server 110, base station 104, one or more TV transmitter 106, mobile telephone base station 104 or any their combination.Then, user terminal 102 is measured pseudorange, and finds the solution aforesaid simultaneous equations.This embodiment is described now.
User terminal 102 is received in the local clock of each TV transmitter 106 and the time migration between the reference clock.User terminal 102 also receives the information of the phase center of describing each TV transmitter 106 from database 112.
User terminal 102 receives the tropospheric velocity of propagation that is calculated by location server 110.In certain embodiments, user terminal 102 receives near the weather information that is described in air themperature, atmospheric pressure and the humidity user terminal 102 from a weather server 114, and uses classic method to determine tropospheric velocity of propagation by this weather information.
User terminal 102 can also be from the base station 104 reception information, the approximate location of its identification user terminal 102.For example, this information can be discerned a cell phone and is positioned at its sub-district or cell sector.This information is used to fuzzy resolution.
User terminal 102 receives the TV signal from one or more TV transmitters 106, and determines the pseudorange between user terminal 102 and each TV transmitter 106.User terminal 102 receives the mobile telephone signal from one or more mobile telephone base stations 104, and determines pseudorange and/or distance between user terminal 102 and mobile telephone base station 104.Then, based on pseudorange, the distance when using, the position of TV transmitter 106, the position of mobile telephone base station 104, user terminal 102 is determined its position.
In any above-mentioned these embodiment, the position of user terminal 102 can use the side-play amount T that calculates during a TV transmitter and the previous position finding for this TV transmitter to determine.The numerical value of T can or keep according to the conventional method storage.
In certain embodiments, the clock offset of user terminal 102 is determined in base station 104.In such an embodiment, only need two transmitters to be used for position finding.Base station 104 is sent to location server 110 with clock offset T, and this server is by the user terminal 102 of position determine to(for) the pseudorange that each transmitter calculated then.
Use the position finding of gsm mobile telephone signal
The gsm mobile telephone signal is frequency division multiple access/time division multiple access (TDMA) (FDMA/TDMA) signal of a kind of 200kHz of having bandwidth and 1625/6=270.83333kbps bit rate.25MHz is used to transmit the total bandwidth that is used to receive with 25MHz, and the GSM signal has the channel that 124 200kHz that respectively do for oneself add a 200kHz protection frequency band.Then, each channel is divided into 8 time slots of being shared by 8 different active users by a kind of minimum offset keying signal modulation of 270.8333kbps Gaussian again by means of tdma frame.Therefore, system has the capacity of 8 * 124=992 time slot.The a pair of 45MHz of having channel at interval is assigned to a given duplex channel.
The GSM signal has 5 kinds of different burst format: normal burst pulse, frequency Correction Burst, synchronization burst, ghost pulse and access burst pulse train.Frequency Correction Burst has simple carrier wave composition except 6 tail bits add the guard time.Because the 0.3GMSK modulation, a string " 0 " bit produces a kind of simple carrier wave, and it has frequency shift (FS) 1625/24kHz=67.7+kHz on nominal carrier frequency.This simple carrier wave is used to proofread and correct its local crystal oscillator by user terminal.Synchronization burst is used to the timing that non-standard 26 bit training sequences carry out with 64 bit training sequences.Ghost pulse does not have data, but same with the normal burst pulsion phase in other respects.Access burst pulse train has 68.25 more much bigger guard spaces, one 41 bit training sequence, and 36 data bits are only arranged.
The form that is used for the normal burst pulse is shown in Fig. 4.This form comprises 3 tail bits 402, succeeded by 57 data bits 404, succeeded by 26 bit synchronous training sequences 406, succeeded by 57 data bits 408, succeeded by 3 tail bits 410, succeeded by 8.25 protection bits 412.
In these different pulse formats, training sequence is known to be used for regularly synchronous bit mode by embodiments of the invention.For the normal burst burst transmissions 8 kinds of different training sequences are arranged, they are by the BCC appointment.Training sequence not only is used to adjust adaptive equalizer but also be used to proofread and correct propagation delay.
User terminal enters system by filing a request on Random Access Channel therein.But in order to make tdma signal become that each tdma frame has 8 train of impulses so that suitably work, must send its TDMA train of impulses with the base station with different time migrations at a distance of the user terminal of different distance, receive them so that sentence appropriate timing, and between each train of impulses, do not overlap in the base station.
For this purpose, the base station sends a distance signal that comprises the timing advance parameter.Certainly if other these type of distance signals are available words, can use them as an alternative.This timing advance parameter has 64 steps separately corresponding to 1 data bit, and corresponding to the one-way propagation time of twice.Therefore, propagate for free space, each increment is the distance of 1.846 microseconds or 1846 feet.Therefore, the timing advance parameter provides from the base station to the user terminal individually and is approximately+range accuracy of/-307.6 yards or 302.7 meters.Although this precision is good unlike may wishing, but it has been effective at the user terminal place, and when the pinpoint accuracy with the TV signal measured value combines, can produce an acceptable solution in the backcountry that only has two TV signal to have good geometry.
The timing advance parameter is used as the employed wherein a kind of signaling channel of GSM and is transmitted.3 Dedicated Control Channel (DCCH) are arranged in the signaling channel group.Have one to be the channel of two-way (between user terminal and base station) slow associated control channel (SACCH) form in these DCCH channels, it comprises 7 bit timing advance informations.The form of SACCH channel is shown in Fig. 5.The every 480ms of these controlling links parameters is measured and is upgraded.
Fig. 6 illustrates a kind of system configuration, and it it seems DTV transmitter 106 and GSM base station 104 that only has two to have good geometry from user terminal 102.Certainly if consider additional GSM base station 104, then available their signal improves the degree of accuracy of position finding.Signal is relayed to location server 110 by GSM base-station transceiver system (BTS) 104, base station controller (BSC) 602 and mobile switching center 604 from user terminal 102.
Gsm system is measured a kind of form that can adopt in the some kinds of forms.An embodiment uses the GSM timing advance parameter that always is provided of standard.Its precision may be good unlike a desired.But, except timing advance with other DTV signal measurements, for example use one or more GSM short message services (SMS) message, also be fed to outside the location server 110, do not need standard GSM operation is added.Then, location server 110 is measured timing advance and is combined with the positional information of base station 104, obtains the position of user terminal 102.
The pseudorange of another examples measure between user terminal 102 and base station 104, and use this pseudorange with the pseudorange between user terminal 102 and DTV transmitter 106, go to obtain position with more high-precision user terminal.This embodiment comprises a pseudorange delay lock loop that the GSM training sequence is operated.This training sequence does not have 100% percent make for the normal burst pulse, but has the percent make of 26/ (156.25 * 8)=2.08%.However, for 1 second averaging time, GSM normal burst pulse training sequence had the processing gain of 270,833 * 0.0208=5633 or 37.5dB.Certainly, can use training sequence in the other types GSM pulse equally.
Except the pseudorange between user terminal 102 and the DTV transmitter 106, other embodiment use one or more timing advances to measure, and one or more pseudorange between user terminal 102 and base station 104.
Fig. 7 illustrates a kind of further improvement that need not, and uses the location solution of GSM timing advance together with the measurement of two DTV signals.In this simple case, the GSM timing advance provides a kind of solution of track, and this track is arc 702 simply, and its radius multiply by the light velocity in the atmosphere corresponding to the timing advance in nanosecond.The angle amplitude of arc 702 is corresponding to the angular coverage of k fan anteena (k-sector antenna), and for 8 sectors, the angle amplitude is the 360/8=45 degree.The solution of these two DTV provides one simply corresponding to the para-curve 704 that postpones difference.Thereby the position answer is the point of crossing 706 of arc 702 and corresponding para-curve 704.Can also find other the scheme of finding the solution.
Fig. 8 illustrates the simplification configuration of a kind of time gated delay lock loop (TGDLL) receiver 800, and in one embodiment, this receiver is used for the local reference clock by lock in time that relatively records and user terminal, thereby measures pseudorange.Time gated DLL at length is disclosed in the U.S. non-temporary patent application sequence number No.10/054 by James J.Spilker and MatthewRabinowitz application on January 22nd, 2002, in 262 " the time gated delay lock loops of digital television signal ", its disclosure is whole in conjunction with as with reference to data at this.
Though Fig. 8 illustrates a kind of delay lock loop of incoherent type, should understand the time gated delay lock loop that also can use the phase dry form.Because the GSM receiver must be worked consistently, in Coherence Mode, exist enough signal levels and clock recovery to remove to operate DLL.
A kind of time gated signal of time gated controller 802 generations, its memoryless unit that turns on and off receiver 800 has only just available and these signals of generation in these unit when the needs signal to save power supply, to make.Time gated controller 802 is to be controlled based on the timing signal of the timing generation of training sequence by local clock 804.Unit in receiver (not shown) front end also can be time gated unit.This has saved appreciable power, makes these embodiment be particularly useful for having the portable set of limited power resource.
The GSM signal that receives is sent to a pair of frequency mixer 808A and 808B by a switch 806 that also is subjected to time gated controller control, here it mixes with the I and the Q sample value of training sequence respectively, and the I of training sequence and Q sample value are provided by training sequence generator 810.After by corresponding intermediate-frequency filter 812A and 812B filtering, the output of frequency mixer 808 drives non-coherent detector (NCD) 814A and 814B respectively.The output of each NCD 814 is by totalizer 816 combinations, and by 818 filtering of DLL loop filter.The output of wave filter 818 drives a digital controlled oscillator with local clock 804 timing (NCO) 820, and drives training sequence generator 810.
TGDLL 800 not only can use 26 bit training sequences in the pulse of GSM normal burst, and can use in other GSM pulses training sequence and from the GSM base station 104 broadcasting various control signals.These diverse ways allow precision that measured value has to be higher than the precision that independent use timing advance parameter is obtained.In certain embodiments, the timing advance parameter is used as the auxiliary use of a kind of search.
Location processor 110 is also taken into account the position of antenna for base station and the fan section of being used by user terminal.In addition, must know the clock timing of base station.If base station clock is locked into GPS or certain other timing sources, this is easy to realize and calculate measure the distance of this clock to antenna in other words.
Use separately the timing advance parameter or measure in these two kinds of methods of pseudorange of GSM base station any and all allow only to carry out position finding with two DTV towers under the good geometry.Certainly, if more base station or DTV tower are arranged, then can obtain extra performance improvement.
Use the position finding of CDMA mobile telephone signal
In the most widely used digital cellular system of great majority of usefulness, having a kind of is benchmark with American I S-95CDMA standard now.This CDMA Cellular System is utilized the spread-spectrum signal for interference and multipath robust.This robustness for interference allows all CDMA cell sites to use identical transmission and frequency acceptance band.For the interference between the cell site being reduced to minimum, based on pseudo noise (PN) bit sequence that is produced by the linear feedback generator, each cdma base station signal uses spread-spectrum to send signal, and here the homophase generator is given by following polynomial expression:
f I(x)＝1+x 2+x 6+x 7+x 8+x 10+x 15 (8)
And the quadrature generator is given by following polynomial expression:
f Q(x)＝1+x 3+x 4+x 5+x 9+x 10+x 11+x 12+x 15 (9)
This all is to have cycle 215-1=32,767 maximum-length shift register sequence.
Each cdma base station signal all uses these same homophases and quadrature PN sequence.Carrier wave of these sequence modulation, its effect are very similar at a modulating data on the high level carrier wave more.The spreading rate that is used for each signal is 1.2288Mcps.Per 26.66 milliseconds of each cycle of this sequence repeats per in other words 2 seconds 75 times.
For reducing to minimum from the interference of the different districts website that uses the same frequency band transmission at the user terminal place, the PN sequence of each cell site is done skew by certain multiple with 64 chips.512 unique side-play amounts are arranged.Different skews is used in base stations all in a zone, interference reduced to minimum and to be helped user terminal to obtain the strongest base station signal.This method that the identical sequence employing that sends in the signal is offset requires all base stations to keep a stable time reference, so that the time synchronized of its transmitter.All CDMA cell sites obtain their time reference by means of the GPS receiver.
The IS-95 digital cellular system is operated in the frequency band identical with current analog cellular frequency band (AMPS), the downlink of its up-link by means of 869-894MHz (user terminal to base station) frequency band and 824-849MHz (base station is to user terminal) frequency band is realized two-way simultaneous communication by use the Frequency Division Duplexing (FDD) of 25MHz on each direction.This 25MHz frequency band is divided into 20 frequency bands on each direction, and wherein the frequency band of each 1.25MHz uses the single carrier wave with PN sequence in homophase and quadrature component, and its spreading rate is 1.2288Mcps.
Each down link signal in above-mentioned 1.25MHz frequency band has 64 channels, comprises a high power pilot channel, low-power synchronizing channel and 62 pagings and Traffic Channel.This pilot channel allows user terminal to go to obtain and the tracking base stations signal.Search by all shift time drifts of PN sequence are arranged, user terminal obtains the strongest signal these unmodulated pilot frequency channel signals from its different base station that finds.This synchronizing channel allows user terminal for selected base station network time synchronized.Each this class downlink channel uses a code word in 64 orthogonal walsh code words, and these code words make utilizes the channel of identical 1.25MHz frequency band to be separated.User terminal utilizes in 64 Walsh code words one to receive from one of them above-mentioned BTS channel.
